Description

Technical Field

[0001] This utility model relates to the field of silicon dioxide production technology, specifically to a dust prevention device for silicon dioxide production. Background Technology

[0002] Silicon dioxide (Silica) is an inorganic compound widely found in nature and is one of the main components of the Earth's crust. It is a hard and brittle solid, insoluble in water, and possesses high chemical and thermal stability. Silicon dioxide has various crystal structures, including quartz, crystal, and wollastonite. Silicon dioxide has wide industrial applications. It is a raw material for manufacturing glass, quartz glass, water glass, optical fibers, important components in the electronics industry, optical instruments, handicrafts, and refractory materials. Furthermore, silicon dioxide is used in the manufacture of silicone rubber, plastics, coatings, and other materials as a filler and reinforcing agent to improve their mechanical properties, wear resistance, and corrosion resistance.

Detailed Implementation

[0054] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0055] like Figures 1 to 6 As shown, an embodiment of this utility model provides a dustproof device for silicon dioxide production, including: a supporting base plate 1 and a dustproof cover 303; it also includes: a transmission part disposed on the supporting base plate 1 for transporting silicon dioxide; a dustproof part disposed on the upper end of the transmission part, connected to the transmission plate via a snap-fit ​​part, and connected to the dustproof cover 303; and an adjustment part disposed on the dustproof part for driving the dustproof cover 303 to disengage from or connect to the transmission part.

[0056] In this embodiment of the utility model, by providing a dust cover 303 on the transmission part, dust will not be diffused into the air when the silicon dioxide moves on the transmission part. The dust cover is snapped together with the transmission part by the snap-fit ​​part, so that the dust cover will not detach when dust protection is required; when the transmission part needs to be cleaned, the dust cover can be easily detached by cooperating with the adjustment part. The support rod 101 provides support for the device.

[0057] like Figures 1 to 6 As shown, the transmission unit includes: two sets of support side plates 102, which are symmetrically arranged on the support base plate 1; a driving roller 502, which is rotatably connected to the support side plates 102 at both ends; several sets of driven rollers 503, which are rotatably connected to the support side plates 102 in a straight line; and a second motor 501, which is mounted on the support side plates 102 and whose output end passes through the support side plates 102 and is connected to a transmission belt at one end of the driving roller 502, and is in close contact with the driving roller 502 and the driven roller 503.

[0058] In this embodiment of the invention, the second motor 501 is started to drive the active roller 502 to rotate. The active and driven rollers 503 drive the conveyor belt 504 to rotate by friction, placing the silicon dioxide from the production step onto the conveyor belt 504 and transporting it to the next process.

[0059] like Figures 1 to 6 As shown, the adjustment part includes: a support member disposed on the support base plate 1 to support the dustproof part; and a first adjustment member disposed on the support member to adjust the protective state of the dustproof cover 303.

[0060] In this embodiment of the utility model, the movement of the dustproof part is made more stable by setting the support member, and the dustproof part is moved on the support member by the first adjusting member, so that the dust cover 303 can be in two working states: working and not working.

[0061] like Figures 1 to 6 As shown, the support includes: a first U-shaped support rod 201, both ends of which are connected to the support base plate 1; a second U-shaped support rod 202, both ends of which are connected to the end of the support base plate 1 away from the first U-shaped support rod 201; and a support top plate 401, one end of which is connected to the first U-shaped support rod 201, and the other end of which is connected to the second U-shaped support rod 202.

[0062] like Figures 1 to 6As shown, the first adjusting component includes: a first fixing plate 402, one end of which is connected to the second U-shaped support rod 202; a telescopic fixing plate 405, one end of which is connected to the first U-shaped support rod 201; a threaded rod 404, one end of which is rotatably connected to the first fixing plate 402, and the other end of which is rotatably connected to the telescopic fixing plate 405; a first motor 403, which is disposed on the first fixing plate 402 and passes through the first fixing plate 402 and is connected to one end of the threaded rod 404; a threaded sleeve 406, which is sleeved on the threaded rod 404; a second electric telescopic rod 205, one end of which is connected to the threaded sleeve 406, and the other end of which is connected to the dustproof part; a first fixing block 203, which is disposed on the first U-shaped support rod 201; and a first electric telescopic rod 204, one end of which is connected to the first fixing block 203, and the other end of which is connected to the dustproof part.

[0063] In this embodiment of the invention, by driving the first motor 403, the threaded rod 404 is rotated, thereby causing the threaded sleeve 406 to move along the threaded rod 404. A limit rod is provided to prevent the threaded sleeve 406 from rotating together with the threaded rod 404 when it rotates. The movement of the threaded sleeve 406 will cause the second electric telescopic rod 205 to move, thereby causing the dustproof part to move to a certain extent. At the same time, the first electric telescopic rod 204 and the second electric telescopic rod 205 will cause the dustproof part to move up and down.

[0064] like Figures 1 to 6 As shown, the dustproof part includes: a first U-shaped dustproof rod 301, the top end of which is connected to the telescopic fixing plate 405; a second fixing block 304, which is disposed at the top end of the first U-shaped dustproof rod 301 and connected to the other end of the first electric telescopic rod 204; a second U-shaped dustproof rod 302, which is connected to the first U-shaped dustproof rod 301 via the dustproof cover 303; a third fixing block 306, which is disposed at the top end of the second U-shaped dustproof rod 302 and connected to the other end of the second electric telescopic rod 205; and a dustproof curtain 305, which is disposed on the first U-shaped dustproof rod 301 and the second U-shaped dustproof rod 302.

[0065] In this embodiment of the utility model, a dust cover 303 is connected between the first U-shaped dustproof rod 301 and the second U-shaped dustproof rod 302. The dust cover 303 is made of flexible material. When the first U-shaped dustproof rod 301 and the second U-shaped dustproof rod 302 move together, the dust cover 303 will fold between the first U-shaped dustproof rod 301 and the second U-shaped dustproof rod 302. When the first U-shaped dustproof rod 301 and the second U-shaped dustproof rod 302 move to both ends of the conveyor belt 504, the dust cover 303 unfolds and completely covers the upper end of the conveyor belt 504 to prevent dust from scattering. At the same time, dust curtains 305 are provided at both ends to further improve the dustproof performance.

[0066] like Figures 1 to 6 As shown, the snap-fit ​​part includes: a guide rod 601, disposed on the support side plate 102; a first movable groove 602, formed in the first U-shaped dustproof rod 301; a snap-fit ​​shaft 603, passing through the first movable groove 602; a first spring 604, one end connected to the first movable groove 602, the other end connected to the snap-fit ​​shaft 603, and sleeved on the snap-fit ​​shaft 603; and a snap-fit ​​block 605, which cooperates with the guide groove on the guide rod 601 and is connected to one end of the snap-fit ​​shaft 603.

[0067] In this embodiment of the invention, when the first U-shaped dustproof rod 301 and the second U-shaped dustproof rod 302 move downwards, the locking block 605 contacts the upper end of the guide rod 601. As they continue to move downwards, the inclined surface of the locking block 605 presses against the guide rod 601, thereby causing the locking block 605 to move inwards towards the first movable groove 602. The locking block 605 presses against the locking shaft 603, simultaneously compressing the first spring 604. Continuing to move downwards, the locking block 605 moves to the guide groove. At this point, the first spring 604 rebounds, causing the locking shaft 603 to move inwards, thereby moving the locking block 605 into the guide groove. At this time, the guide rod 601 limits the movement of the second U-shaped dustproof rod 302, preventing external force from causing the second U-shaped dustproof rod 302 to deviate. When detachment is required, simply move the protective part upwards, and the locking block 605 will automatically detach from the guide groove.

[0068] Working principle: Initially as Figure 3In this state, the protective cover protects the conveyor belt 504. First, by simultaneously activating the first electric telescopic rod 204 and the second electric telescopic rod 205, the first U-shaped dustproof rod 301 and the second U-shaped dustproof rod 302 are moved downwards until the locking block 605 contacts the upper end of the guide rod 601. Continuing to move downwards, the inclined surface of the locking block 605 presses against the guide rod 601, thereby causing the locking block 605 to move inwards towards the first movable groove 602. The locking block 605 presses against the locking shaft 603, simultaneously compressing the first spring 604. Continuing to move downwards, the locking block 605 moves to the guide groove. At this point, the first spring 604 rebounds, causing the locking shaft 603 to move inwards, thereby causing the locking block 605 to move towards the guide groove. Inside the guide groove, the guide rod 601 limits the second U-shaped dustproof rod 302. Then, by starting the first motor 403, the threaded rod 404 rotates, causing the threaded sleeve 406 to move along the threaded rod 404. The threaded sleeve 406, via the second electric telescopic rod 205, moves the second U-shaped dustproof rod 302 away from the first U-shaped dustproof rod 301 until it reaches the other end of the conveyor belt 504. At this point, the locking block 605 slides along the guide groove on the guide rod 601, limiting the second U-shaped dustproof rod 302, thus completing the installation of the dust cover 303 to achieve the dustproof effect. When it is necessary to remove the dust cover 303 to clean the conveyor belt 504, simply reverse the operation, which is quite convenient.

[0069] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
